Thumbnail Filmstrip of CPIFF-2P-25 | 1/4" Inline Check Valve with 25 psi spring Images
CPIFF Series Soft Seat Check Valves provide a positive shut off to prevent reverse flow. CPIFF Series check valves are designed to protect hydraulic systems from fluid back pressure. The poppet is streamlined with minimum restriction of flow in one direction. Flow is blocked in the reverse direction as the soft seat creates a leak free seal in the closed position. These in-line unidirectional valves are available in sizes 1/4” to 1” with a pressure rating up to 5000 psi. Standard spring crack pressures are shown in the part number table. Other crack pressures available upon request.
Features:
1. Fluorocarbon poppet seal is standard.
2. Steel construction
3. Optional crack pressures available on request

Questions & Answers
Popular Questions
When installing O-rings, a suitable lubricant should be used to reduce friction and prevent damage. A tool called an O-ring installation tool can also be used to ensure proper placement and avoid twisting or pinching the O-ring. This information is found on the Global O-Ring and Seal website (https://www.globaloring.com/o-ring-in...) under the sections "Lubrication" and "Tools." Moreover, the surface where the O-ring will be installed must be clean and free from sharp edges, burrs, or spiral machined finishes to prevent damage. This information is found on the Parker Hannifin O-Ring Handbook (https://www.parker.com/literature/O-R...) on page 6-3 under the section "Surface Finish and Hardness."
